Calculate the standard cell potential (e∘) for the reaction x(s)+y+(aq)→x+(aq)+y(s) if k = 8.97×10−3. express your answer to three significant figures and include the appropriate units. view available hint(s)

The standard cell potential (E∘) for the reaction  is -0.121 V

Explanation:

The reaction is:

Relation between standard Gibbs free energy and equilibrium constant follows:

where,

= Standard Gibbs free energy = ?

R = Gas constant =

T = temperature = 298 K

K= equilibrium constant =

Putting values in above equation, we get:

To calculate standard Gibbs free energy, we use the equation:

Where,

n = number of electrons transferred = 1

F = Faradays constant = 96500 C

= standard cell potential = ?

Putting values in above equation, we get:

Thus standard cell potential (E∘) for the reaction  is -0.121 V
